Merge tag 'dmaengine-4.11-rc1' of git://git.infradead.org/users/vkoul/slave-dma
Pull dmaengine updates from Vinod Koul: "This time we fairly boring and bit small update. - Support for Intel iDMA 32-bit hardware - deprecate broken support for channel switching in async_tx - bunch of updates on stm32-dma - Cyclic support for zx dma and making in generic zx dma driver - Small updates to bunch of other drivers" * tag 'dmaengine-4.11-rc1' of git://git.infradead.org/users/vkoul/slave-dma: (29 commits) async_tx: deprecate broken support for channel switching dmaengine: rcar-dmac: Widen DMA mask to 40 bits dmaengine: sun6i: allow build on ARM64 platforms (sun50i) dmaengine: Provide a wrapper for memcpy operations dmaengine: zx: fix build warning dmaengine: dw: we do support Merrifield SoC in PCI mode dmaengine: dw: add support of iDMA 32-bit hardware dmaengine: dw: introduce register mappings for iDMA 32-bit dmaengine: dw: introduce block2bytes() and bytes2block() dmaengine: dw: extract dwc_chan_pause() for future use dmaengine: dw: replace convert_burst() with one liner dmaengine: dw: register IRQ and DMA pool with instance ID dmaengine: dw: Fix data corruption in large device to memory transfers dmaengine: ste_dma40: indicate granularity on channels dmaengine: ste_dma40: indicate directions on channels dmaengine: stm32-dma: Add error messages if xlate fails dmaengine: dw: pci: remove LPE Audio DMA ID dmaengine: stm32-dma: Add max_burst support dmaengine: stm32-dma: Add synchronization support dmaengine: stm32-dma: Fix residue computation issue in cyclic mode ...
